单选题Hunting for a job late last year, lawyer Gant Redmon stumbled across Career Builder, a job database on the Internet. He searched it with no success but was attracted by the site"s "personal search agent". It"s an interactive feature that lets visitors key in job criteria such as location, title, and salary, then e-mail them when a matching position is posted in the database. Redmon chose the key words legal, intellectual property, and Washington , D. C. Three weeks later, he got his first notification of an opening. "I struck gold," says Redmon, who e-mailed his resume to the employer and won a position as in-house counsel for a company. With thousands of career-related sites on the Internet, finding promising openings can be time consuming and inefficient. Search agents reduce the need for repeated visits to the databases. But although a search agent worked for Redmon, career experts see drawbacks. Narrowing your criteria, for example, may work against you, "Every time you answer a question, you eliminate a possibility," says one expert. For any job search, you should start with a narrow concept what you think you want to do— then broaden it. "None of these programs do that," says another expert. "There"s no career counseling implicit in all of this." Instead, the best strategy is to use the agent as a kind of tip service to keep abreast of jobs in a particular database; when you get an e-mail, consider it a reminder to check the database again. "I would not rely on agents for finding everything that is added to a database that might interest me," says the author of a job-searching guide. Some sites design their agents to tempt job hunters to return. When Career Site"s agent sends out messages to those who have signed up for its service, for example, it includes only three potential jobs—those it considers the best matches. There may be more matches in the database; job hunters will have to visit the site again to find them—and they do. "On the day after we send our messages, we see a sharp increase in our traffic," says Seth Peets, vice president of marketing for Career Site. Even those who aren"t hunting for jobs may find search agents worthwhile. Some use them to keep a close watch on the demand for their line of work or gather information on compensation to arm themselves when negotiating for a raise. Although happily employed, Redmon maintains his agent at Career Builder. "You always keep your eyes open," he says. Working with a personal search agent means having another set of eyes looking out for you.

单选题The man who invented Coca-Cola was not a native Atlantan, but on the day of his funeral every drugstore in town testimonially shut up shop. He was John Styth Pemberton, born in 1831 in Knoxville, Georgia, eighty miles away. Sometimes known as Doctor, Pemberton was a pharmacist who, during the Civil War, led a cavalry troop under General Joe Wheeler. He settled in Atlanta in 1869, and soon began brewing such patent medicines as Triplex Liver Pills and Globe of Flower Cough Syrup. In 1885, he registered a trademark for something called French Wine Coca—Ideal Nerve and Tonic Stimulant; a few months later he formed the Pemberton Chemical Company and recruited the services of a bookkeeper named Frank M. Robinson, who not only had a good head for figures but, attached to it, so exceptional a nose that he could audit the composition of a batch of syrup merely by sniffling it. In 1886—year in which, as contemporary Coca-Cola officials like to point out, Conan Doyle unveiled Sherlock Holmes and France unveiled the Statue of Liberty—Pemberton unveiled a syrup that he called Coca-Cola. It was a modification of his French Wine Coca. He had taken out the wine and added a pinch of caffeine, and, when the end product tasted awful, had thrown in some extract of cola nut and a few other oils, blending the mixture in a three-legged iron pot in his back yard and swishing it around with an oar. He distributed it to soda fountains in used beer bottles, and Robinson, with his flowing bookkeeper's script, presently devised a label, on which "Coca-Cola" was written in the fashion that is still employed. Pemberton looked upon his mixture less as a refreshment than as a headache cure, especially for people whose headache could be traced to over-indulgence. On a morning late in 1886, one such victim of the night before dragged himself into an Atlanta drugstore and asked for a dollop of Coca-Cola. Druggists customarily stirred a tea-spoonful of syrup into a glass of water, but in this instance the man on duty was too lazy to walk to the fresh-water tap, a couple of feet off. Instead, he mixed the syrup with some soda water, which was closer at hand. The suffering customer perked up almost at once, and word quickly spread that the best Coca-Cola was a fizzy one.

单选题Britain and Spain have the highest proportion of cocaine users in the EU, according to a pan-European drugs survey published today. The European Monitoring Center for Drugs and Drug Addiction 2004 report found 2% of all adults in the UK and Spain reported recent cocaine use, close to figures for the US, compared to less than 1% across the EU as a whole. It reported that cocaine use was increasing in Denmark and Germany and that more Europeans were seeking treatment for cocaine-related problems. In most countries, treatment is demanded for the use of cocaine powder rather than smoked crack cocaine--but in the Netherlands around two-thirds of cocaine treatment demands were crack related. Crack use was increasing in a number of cities in Germany, Spain, France and the UK, the survey found. Heroin use is relatively stable in many EU countries, with new users failing, but limited data from the new member states in central and Eastern Europe may mask localized increases. Deep concern surrounds the continuing HIV epidemic in some of the new EU member states and their bordering countries, where heroin injecting is more common than it is the western states. Estonia, Latvia, Russia and Ukraine are the countries with the fastest growing HIV epidemic in the world, though 'there are signs it is stabilizing in the Baltic states. The director of the EU drugs agency, Georges Estievenart, identified positive signs in the downwards trend of drug-related deaths and better access to treatment and care but warned of future problems. "There is a risk that some of these positive trends may be short-lived and real concerns surround potential drug epidemics, particularly in some of the new members of our Union." "And we should not forget that drug use in general remains at historically high levels-many countries are reporting rising cocaine use and more people are using cannabis and ecstasy in parts of Europe." The Home Office minister, Caroline Flint, said the report was based on old data and the British Crime Survey showed that crack and cocaine use had stabilized. "We are not complacent about the drugs situation in Britain," she said. "Drug use is still too high and we are planning new legislation aimed at getting more users into treatment--including testing on arrest--and strengthening police powers to tackle drug dealers./
